About Me

My photo
Canberra-based naturalist, conservationist, educator since 1980. I’m passionate about the natural world (especially the southern hemisphere), and trying to understand it and to share such understandings. To that aim I’ve written several books (most recently 'Birds in Their Habitats' and 'Australian Bird Names; origins and meanings'), run tours all over Australia, and for the last decade to South America, done a lot of ABC radio work, chaired a government environmental advisory committee and taught many adult education classes – and of course presented this blog, since 2012. I am the recipient of the Australian Natural History Medallion, the Australian Plants Award and most recently a Medal of the Order of Australia for ‘services to conservation and the environment’. I live happily in suburban Duffy with my partner Louise surrounded by a dense native garden and lots of birds.

On This Day, 18 September: Chile's National Day, featuring two saltos.

On this day in 1810 the Spanish colonial governor of Chile was deposed and replaced by a Council of seven, based in Santiago; this was only the beginning of the end of Spanish rule, but it is marked now as the first of two consecutive Fiestas Patrias, effectively Chile's national days. Chile was my first experience of South America, and as such retains a special place in my heart. My experience of it has so far been limited to the south, though in the next 12 months I plan to rectify that by visiting the Atacama. However it means that a strong part of my impression of Chile is water and in paying a tribute to the country on its special day, I'm going to do so by introducing you to two very special and spectacular saltos - literally a jump, but also meaning waterfall or cascade.

The first is Salto Petrohué in Vicente Pérez Rosales National Park, inland from the bustling Puerto Montt, on the Petrohué River soon after it flows out of Lago Todos los Santos. The second is much further south, in the sublime Torres del Paine National Park. Salto Grande - the 'big falls' - forms in a slot canyon between Lago Nordenskjöld and Lago Pehoé. 
Location of Salto Petrohué shown (approximately!) by end of red arrow;
that of Salto Grande by end of brown arrow.
The settings of both are superb. 
Looking east along Lago Todos Santos to the Andean spine; the mountains, including Tronodor, are
on the Chilean-Argentinian border. The Petrohué flows west from the right of the photo.
The mountains around Lago Todos Santos are still visible from the saltos, a little downstream.
The top of Salto Petrohué, with mighty Puntiagudo in the background.
(The name simply means 'pointy'.)
From there the water roars down through a narrow slot.
The rocks are laval basalt, very tough but still being gradually worn away.
Below the falls the river runs over shallow bars and through rocky channels, sometimes still white, sometimes relatively peaceful.
Rio Petrohué flowing through cool temperate rainforest downstream of the falls
(above and below).

While the falls are the obvious attraction, the forest itself is well worthy of our attention too, especially if we have an eye to the Gondwanan connections of the plants, a striking aspect to those of us lucky enough to visit from other southern lands.
Notro, Embothrium coccineum, overhanging the Petrohué River.
This member of the family Proteaceae bears a striking resemblance to the
Australian waratahs, Telopea spp., in the same family.
The characteristic blue of the water is due to the presence of fine suspended particles of silt.
Weinmannia trichosperma, family Cunonicacae - another Gondwanan family.
Escallonia rubra; its family, Escallionaceae, is mostly found in South America, with
a smaller focus in Australia.
But let's fly south now, to the second of our saltos to celebrate Chile's day. It too has a spectacular setting, between two of the lakes for which Torres del Paine is famous (among many other things!). 
Lago Nordenskjöld, with the Towers (Torres) behind it.
Not a very Spanish (or Tehuelche!) name, you may well think; it was named for Swedish
geologist and explorer Otto Nordenskjöld, who investigated the area in the 1920s.
Lago Pehoé whipped up by the winds that are typical of the area; I've been nearly knocked off my
feet by them while visiting Salto Grande.

Pehoé is lower than Nordenskjöld, causing the waters to rush into Pehoé with dramatic force.
Upstream of the salto, with the Horns (the Curenos) in the background.

The falls, above and below; the latter shows Lago Pehoé in the background.


Another view of the mighty Cuernos, looking back from Salto Grande.
And, as everywhere, there are plants and animals to admire too, including the ubiquitous Notro.
Notro by the Salto Grande.
Southern House Wren Troglogdytes musculus, Salto Grande. This bird will be instantly familiar to my northern
hemisphere friends, though the Eurasian species has now been separated. Many ornithologists recognise
just one species (T. aedon) from Canada to Tierra del Fuego, but the South Americans disagree.

Male Austral Negrito Lessonia rufa, an equally widespread bird in the south.
It is one of the vast group of South American Tyrant Flycatchers which makes
South American birding such a challenge and a joy to the rest of us.

So, Happy Day Chile, and thanks for sharing your wonderful saltos with us!

BACK ON WEDNESDAY

Before reading the post (why confuse matters with mere facts?) I had assumed that '2 saltos' was about 2 sailors - presumably the fathers of the country.

I got to this - with hindsight daft - conclusion through a combination of the English vernacular "salt" for sailor and the Australian habit of appending 'o' to any word unfortunate enough to end with a consonant!

In the event the content was far more pleasing to the eye (and the mind)!

Martin, among the many things I like about you are your creativity and self-deprecation!
